Information on number of saturated fusion systems
FACTS TO CHECK AGAINST FOR FUSION SYSTEMS:
For an abelian group of prime power order: identity functor controls strong fusion for saturated fusion system on abelian group|classification of saturated fusion systems on abelian group of prime power order
| Group | GAP ID second part | Hall-Senior number | Nilpotency class | Number of saturated fusion systems (strict counting) | Number of saturated fusion systems up to isomorphism | Is the group resistant? In other words, does the identity functor control strong fusion in every saturated fusion system? (Yes if abelian) | Is it a group of prime power order with no exotic fusion system? |
